La presente invención se refiere a un zapato, y más concretamente, a un zapato con dispositivo antideslizante que es flexible y reemplazable. The present invention relates to a shoe, and more specifically, to a shoe with a non-slip device that is flexible and replaceable.
Un zapato antideslizante resistente al agua convencional incluye una plantilla que incluye múltiples resaltes que proporcionan una función antideslizante, y un conjunto de picos están formados solidarios de la plantilla y sobresalen hacia fuera de la parte inferior de la plantilla. Los extremos distales de los picos se encuentran a nivel con los resaltes. Un empeine está conectado solidario de la parte superior de la plantilla. Cada uno de los picos incluye varias puntas que se extienden hacia el exterior. Las espigas y las puntas están provistas de arrugas con el fin de conectarse firmemente a la plantilla. Los resaltes y están situados alternativamente respecto a los picos. Por lo tanto, los picos pueden morder la superficie deslizante y los resaltes y proporcionar un mayor rozamiento. A conventional water-resistant non-slip shoe includes a insole that includes multiple protrusions that provide a non-slip function, and a set of spikes are formed integral with the insole and protrude outward from the bottom of the insole. The distal ends of the peaks are level with the projections. An instep is connected in solidarity with the upper part of the template. Each of the peaks includes several points that extend outwards. The spikes and tips are provided with wrinkles in order to connect firmly to the template. The projections and are located alternately with respect to the peaks. Therefore, the peaks can bite the sliding surface and the projections and provide greater friction.
Sin embargo, los picos se extienden a ciertas zonas de la parte inferior del zapato de manera que cuando la superficie que pisa el zapato incluye una superficie irregular, los picos podrían no quedar encima para morder la superficie y el usuario podría resbalar. However, the spikes extend to certain areas of the bottom of the shoe so that when the surface stepped on the shoe includes an irregular surface, the spikes may not be left over to bite the surface and the user could slip.
Además, el zapato antideslizante generalmente incluye una suela exterior delgada que permite al usuario sentir el estado geográfico de la superficie que pisa. Con el fin de hacer que el pico quede conectado firmemente a la plantilla, el conjunto de picos convencionales presenta forma de T de modo que el usuario no se siente cómodo. In addition, the non-slip shoe generally includes a thin outer sole that allows the user to feel the geographical state of the stepping surface. In order to make the peak firmly connected to the template, the set of conventional peaks is T-shaped so that the user does not feel comfortable.
Por otra parte, el conjunto de picos está formado solidario de la plantilla de modo que no puede reciclarse y reutilizarse. On the other hand, the set of peaks is formed integral with the template so that it cannot be recycled and reused.
La presente invención pretende disponer un zapato con un dispositivo antideslizante que incluye unas almohadillas flexibles con picos rígidos insertados en las ranuras de las almohadillas flexibles. El zapato es cómodo y el dispositivo antideslizante puede reciclarse y sustituirse. The present invention aims to provide a shoe with a non-slip device that includes flexible pads with rigid spikes inserted in the grooves of the flexible pads. The shoe is comfortable and the non-slip device can be recycled and replaced.

La figura 5 es una vista en despiece para mostrar otra realización del zapato de la presente invención. Figure 5 is an exploded view to show another embodiment of the shoe of the present invention.
Haciendo referencia a las figuras 1 a 4, el zapato de la presente invención comprende dos almohadillas flexibles 1 y cada una está realizada en un material suave y antideslizante. Cada almohadilla flexible 1 presenta múltiples ranuras 11 definidas en las mismas y dos zonas de restricción 12 están conectadas a dos extremos de cada ranura 11. Dos conjuntos de picos 2 tienen, cada uno, picos 21 y dos secciones extremas 22 se extienden desde dos extremos de cada pico 21. Los picos 21 están realizados en un material duro y se insertan en las ranuras 11 de la almohadilla flexible 1. El borde distal 211 de los picos 21 queda a nivel con la parte inferior 13 de la almohadilla flexible 1. La anchura de cada uno de los picos 21 es mayor que una anchura de la almohadilla flexible 1 donde conectan los picos 21 de modo que cuando los picos 21 se insertan en las ranuras 11, las secciones extremas 22 sobresalen hacia fuera desde dos lados de la almohadilla flexible 1. Por lo tanto, los picos 21 no se caen de las ranuras 11. Referring to Figures 1 to 4, the shoe of the present invention comprises two flexible pads 1 and each is made of a soft and non-slip material. Each flexible pad 1 has multiple grooves 11 defined therein and two restriction zones 12 are connected to two ends of each groove 11. Two sets of peaks 2 each have peaks 21 and two end sections 22 extend from two ends. of each peak 21. The peaks 21 are made of a hard material and are inserted into the grooves 11 of the flexible pad 1. The distal edge 211 of the peaks 21 is level with the bottom 13 of the flexible pad 1. The width of each of the peaks 21 is greater than a width of the flexible pad 1 where the peaks 21 connect so that when the peaks 21 are inserted into the grooves 11, the end sections 22 protrude outward from two sides of the pad flexible 1. Therefore, the peaks 21 do not fall out of the slots 11.
Una parte media 3 tiene un cuello 31 en una periferia de la misma de manera que se forma un espacio ranurado. A través del extremo interior 32 de la parte media 3 se definen dos orificios 33. Los tamaños de los orificios 33 se corresponden con los tamaños de las almohadillas flexibles 1 que se acoplan a los orificios 33. Debido a que las secciones extremas 22 se extienden más allá de las zonas de restricción 12 de las almohadillas 1, las almohadillas flexibles 1 no se caen de los orificios 33. A middle part 3 has a neck 31 on a periphery thereof so that a slotted space is formed. Through the inner end 32 of the middle part 3, two holes 33 are defined. The sizes of the holes 33 correspond to the sizes of the flexible pads 1 that fit the holes 33. Because the end sections 22 extend beyond the restriction zones 12 of the pads 1, the flexible pads 1 do not fall out of the holes 33.
Una plantilla 4 se encuentra situada en una parte superior de la parte media 3 por moldeo por inyección para cubrir las almohadillas flexibles 1 y el conjunto de picos 2. La plantilla 4 está conectada solidaria de un extremo interior 32 de la parte media 3, o la plantilla 4 y la parte media 3 son dos piezas individuales. A template 4 is located in an upper part of the middle part 3 by injection molding to cover the flexible pads 1 and the set of spikes 2. The template 4 is connected integral with an inner end 32 of the middle part 3, or the template 4 and the middle part 3 are two individual pieces.
Un empeine 5 tiene su altura de acuerdo con el diseño de los zapatos y está conectado al cuello 31 de la parte media 3 por cosido, prensado con calor o encolado. Entre el empeine y la parte media 5 se define un espacio 3. Después de conectar entre si el empeine 5 y la parte media 3, la combinación del empeine 5 y la parte media 3 es procesada por una máquina (no mostrada) para llenar el espacio con material fundido y el material fundido recubierto también recubre el exterior del empeine 5 y la parte media 3. Las almohadillas flexibles 1 y el conjunto de picos sobresalen de la parte inferior del empeine 5. An instep 5 has its height according to the design of the shoes and is connected to the neck 31 of the middle part 3 by sewing, hot pressing or gluing. Between the instep and the middle part 5 a space 3 is defined. After connecting the instep 5 and the middle part 3 together, the combination of the instep 5 and the middle part 3 is processed by a machine (not shown) to fill the space with molten material and the coated molten material also covers the exterior of the instep 5 and the middle part 3. The flexible pads 1 and the set of peaks protrude from the bottom of the instep 5.
Una parte de la suela exterior 6 tiene un espacio en el que el empeine 5 y la parte media 3 quedan alojados firmemente. La parte de la suela exterior 6 está conectada al empeine 5 por moldeo por inyección. Las almohadillas flexibles 1 y el conjunto de picos 2 sobresalen hacia fuera de la parte inferior de la parte de la suela exterior 6. A part of the outer sole 6 has a space in which the instep 5 and the middle part 3 are firmly housed. The part of the outer sole 6 is connected to the instep 5 by injection molding. Flexible pads 1 and spike assembly 2 protrude outward from the bottom of the outer sole part 6.
Cuando no se utilizan los zapatos, la almohadilla flexible 1 y el conjunto de picos 2 están a nivel con la parte inferior de la parte de la suela exterior 6, quedando los picos 21 ocultos en las almohadillas flexibles 1. Cuando el usuario lleva los zapatos y aplica una fuerza a los zapatos, como que las almohadillas flexibles 1 están realizadas en un material blando, el cual se estrecha por la fuerza y la fuerza de reacción de la superficie que pisan los zapatos, los picos 21 sobresalen hacia fuera de las almohadillas flexibles 1 para tener la función antideslizante. Las almohadillas flexibles 1 proporcionan un rozamiento adecuado para reforzar la función antideslizante. Además, los picos 21 están son picos a modo de placa alargada y están situados sustancialmente paralelos entre sí, de modo que cuando se pisa una superficie irregular, habrá más de dos o tres puntos de contacto entre los picos 21 y la superficie. When the shoes are not used, the flexible pad 1 and the set of spikes 2 are level with the bottom of the part of the outer sole 6, the spikes 21 being hidden in the flexible pads 1. When the user wears the shoes and applies a force to the shoes, such as that the flexible pads 1 are made of a soft material, which is narrowed by the force and the reaction force of the surface stepped on the shoes, the spikes 21 protrude out from the pads Flexible 1 to have the non-slip function. Flexible pads 1 provide adequate friction to reinforce the non-slip function. In addition, the peaks 21 are peaks as an elongated plate and are located substantially parallel to each other, so that when an irregular surface is stepped on, there will be more than two or three points of contact between the peaks 21 and the surface.
La plantilla 4 se encuentra situada entre la parte superior de los conjuntos de picos 2 y la parte inferior del empeine 5, para que los usuarios se sientan cómodos. The template 4 is located between the top of the spike assemblies 2 and the bottom of the instep 5, so that the users feel comfortable.
La figura 5 muestra otra realización del zapato de la presente invención, en la que los cambios respecto a la realización anterior son que la plantilla 4 está realizada según el tamaño del empeine 5 y la periferia interior de la parte media 3, y la parte inferior de la plantilla 4 incluye unas piezas de acoplamiento 42 que se extienden desde la misma. Las piezas de acoplamiento 42 tienen cada una un saliente 421 en un extremo distal de las mismas. Figure 5 shows another embodiment of the shoe of the present invention, in which the changes with respect to the previous embodiment are that the insole 4 is made according to the size of the instep 5 and the inner periphery of the middle part 3, and the bottom part of the template 4 includes coupling parts 42 extending therefrom. The coupling pieces 42 each have a projection 421 at a distal end thereof.
La parte media 3 tiene un cuello 31 en una periferia de la misma, y dos orificios 33 y a través de la parte media 3 se definen unos orificios de acoplamiento 321. Las piezas de acoplamiento 42 se acoplan a los orificios de acoplamiento 321 y los salientes 421 restringen la separación de las piezas de acoplamiento 42 de los orificios de acoplamiento 321. Cuando las espigas 21 se insertan en las ranuras 11 y las almohadillas flexibles 1 se acoplan a los orificios 33, la plantilla 4 se pone sobre el extremo interior de la parte media 3 simplemente insertando las piezas de acoplamiento 42 en los orificios de acoplamiento 321. Esto puede ahorrar tiempo de moldeo por inyección. De esta manera se ahorra en costes de moldeo por inyección y también se ahorra en tiempo de espera para se seque la plantilla 4. The middle part 3 has a neck 31 on a periphery thereof, and two holes 33 and through the middle part 3 coupling holes 321. The coupling parts 42 are coupled to the coupling holes 321 and the projections 421 restrict the separation of the coupling parts 42 from the coupling holes 321. When the pins 21 are inserted into the slots 11 and the flexible pads 1 are coupled to the holes 33, the template 4 is placed on the inner end of the middle part 3 simply by inserting the coupling parts 42 into the coupling holes 321. This can save injection molding time. This saves on injection molding costs and also saves on waiting time for template 4 to dry.
Debido a que la plantilla 4 está conectada a la parte media 3 por el acoplamiento de las piezas de acoplamiento 42 en los orificios de acoplamiento 321, cuando se requiere reemplazar el conjunto de picos 2 o las almohadillas flexibles 1, la plantilla 4 puede quitarse fácilmente de la parte media 3 empujando las piezas de acoplamiento 42 desde los orificios de acoplamiento 321. Las almohadillas flexibles 1 quitadas y el conjunto de picos 2 pueden reciclarse y mantenerse. Because the template 4 is connected to the middle part 3 by the coupling of the coupling parts 42 in the coupling holes 321, when it is required to replace the spike assembly 2 or the flexible pads 1, the template 4 can be easily removed from the middle part 3 by pushing the coupling parts 42 from the coupling holes 321. The flexible pads 1 removed and the spike assembly 2 can be recycled and maintained.
Aunque se ha mostrado y descrito la realización de acuerdo con la presente invención, debería ser claro para los expertos en la materia que pueden realizarse otras realizaciones sin apartarse del alcance de la presente invención. Although the embodiment according to the present invention has been shown and described, it should be clear to those skilled in the art that other embodiments can be made without departing from the scope of the present invention.
